Which Fairy Tale Characters Do You Want to See on Once Upon a Time?

Captain Hook may soon come across Dr. Frankenstein. Not a sentence you'd normally hear in regards to a television show, right? That's the beauty of Once Upon a Time.

In the land of Once, it seems any character from any genre — even Star Wars! — can be introduced into the fold. Most of the well-known fairy tale characters — Snow White (Ginnifer Goodwin), the Evil Queen (Lana Parrilla) and Prince Charming (Josh Dallas), among them — are already regular fixtures on the ABC fantasy drama, but what about familiar faces from The Little Mermaidor The Wizard of Oz? Both are alreadyon theproducers' minds, which raises the question: Which other fairy tale characters would you like to see on Once Upon a Time?

Are you dying to see street rat Aladdin venture to Storybrooke from Agrabah? Robin Hood would probably make for another good Emma (Jennifer Morrison) love interest. Would they go too far by introducing Tron? Executive producers Adam Horowitz and Edward Kitsis do have plenty of knowledge in that area.
